The value of the unknown number which on multiplication with 4 will give 60 is x = 15.
Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication and division.
Given that result is 60 when the number 4 is multiplied by the number x,
The value of the unknown number will be calculated as:-
4 x ( X ) = 60
Divide the number 60 by the number 4 to get the value of x,
X = 60 / 4
X = 15
Therefore, the value of the unknown number will be 15.

To organize 169 students in a square formation, we find the square root of 169, which is 13, so there should be 13 students in each row.
The question pertains to arranging 169 students in a square formation for a photo. When we arrange anything in a square formation, we are essentially arranging them equally in rows and columns. Therefore, by taking the square root of the total number of students, which is 169, this will tell us the number of students that should be arranged in each row and the number of rows required.
A square root of a number is that value which, when multiplied by itself, gives the original number. The square root of 169 is 13. So, for a square formation, there should be 13 students in each row.

(Set up the rational equation, and solve for x!) PLEASE HELP ME
Answer:
5 Male fishes, and 15 Female fishes
Step-by-step explanation:
We have two unknowns: The number of lady fishes (let's represent this number with "L"), and the number of male fishes (let's name this unknown number "M"). So now we need to create two equations to help us solve for these unknowns.
Use the actual sentences they give you to create the equations:
a) "75% of the total number of fishes are female"
Notice that the total number of fishes is the addition of the number of ladies plus the number of males; that is the total is "L+M". According to the sentence, 75% (which in math terms is written as "0.75") of this total number equals the number of lady fishes:
now we work a little the algebra indicated in this equation to simplify it a bit:
which tells us that the number of lady fishes is 3 times thenumber of male fishes.
b) Now the second equation based on the words:
"Lady fishes are 5 more than twice the male fishes"
"Twice the male fishes" can be written as: "2M"
so now we write this sentence as:
Now we combine the two equations by using in the second one the replacement for "L" in terms of "M" that we found in the first equation (that is: "L = 3 M") , so we obtain an equation with just one unknown (M) and we can solve for it:
Which tells us that the number of male fishes in the tank is "5".
We can use now our first simplified equation to find the number of lady fishes:
So, there are 15 female fishes in the tank.
